This is my first set of Dellortos. Never even played with a set of Webers. I cant seem to adjust cylinder #2. Mixture screw can be turned in all the way and engine runs the same. If I pull the spark plug wire on #2 engine runs the same. If I pull any of the others engine runs worse. I changed the distributor and wires and did not help. Also checked my compression on all cylinders and they were even 115 - 120. These are new pistons and rings and havent run this enough to seat them yet. I'm guessing its fuel related. Is this a common problem with these carbs? My plan was pulling the jets out and blowing them out when I get home. Any carb experts willing to give some advice?
Thanks, Scott |

Pull the idle jet and lightly blow air into it; watch for any debris coming out of the small hole next to the jet (that's the air inlet port). Then pull the idle mixture screw and blow lightly through there as well.
The "jet doctor" plugs that small idle air hole with a lead shot ball and replaces the idle jet holder with a taller tube arrangement like the main jet uses. |
